Nozzle structure of burner

Abstract

A nozzle structure of a burner includes: a housing having an exhaust opening penetratingly-formed at an upper surface thereof, and having therein an accommodation space communicated with the exhaust opening; a fuel supply member connected to the housing such that one end thereof communicates with one side of the accommodation space, for supply of liquid fuel to inside of the accommodation space; a fuel supply controller accommodated in the accommodation space so as to be movable up and down, and having a fuel supply micro-control member at an end thereof, the fuel supply micro-control member configured to micro-control the amount of fuel to be supplied, by being selectively inserted into or separated from the exhaust opening as it moves up and down; and a heating pipe connected to two sides of an outer surface of the housing with different heights, so as to communicate with the accommodation space.

What is claimed is: 
     
       1. A nozzle structure of a burner, comprising:
 a housing having an exhaust opening penetratingly-formed at an upper surface thereof, and having therein a single accommodation space communicated with the exhaust opening, 
 wherein the single accommodation space includes: a supply portion disposed at an upper side thereof and communicated with the exhaust opening; an accommodation portion disposed at a lower side thereof; and a communication portion disposed between the supply portion and the accommodation portion, and 
 wherein the communication portion has an inner diameter larger than that of the supply portion, a first tapered boundary region being formed between the supply portion and the communication portion, and the accommodation portion has an inner diameter larger than that of the communication portion, a second tapered boundary region being formed between the communication portion and the accommodation portion; 
 a fuel supply member connected to the accommodation portion of the single accommodation space for supply of a liquid fuel to inside of the single accommodation space, the fuel supply member being connected to a position lower than the second tapered boundary region; 
 a fuel supply controller accommodated inside the single accommodation space so as to be movable up and down, and having a fuel supply micro-control member at an end thereof, wherein the fuel supply micro-control member is configured to micro-control an amount of the liquid fuel to be supplied, by being inserted into or separated from the exhaust opening as the fuel supply controller moves up and down; and 
 a heating pipe, one end of which is connected to the communication portion of the single accommodation space, which passes through a combustion portion of the burner, and the other end of which is connected to the supply portion of the single accommodation space, the one end of the heating pipe being connected to a position lower than the first tapered region, such that the liquid fuel supplied into the single accommodation space flows the heating pipe and is vaporized to be supplied into the exhaust opening via the supply portion of the single accommodation space, 
 wherein the fuel supply controller includes: 
 a shielding member disposed in the accommodation portion, and configured to block a communication hole of the fuel supply member as the fuel supply controller moves up and down; and 
 an extension member extending from an upper surface of the shielding member with a predetermined length, having a diameter smaller than that of the shielding member, and disposed in the communication portion. 
 
     
     
       2. The nozzle structure of a burner of  claim 1 , wherein the exhaust opening has a diameter gradually decreased toward an upper side of the exhaust opening. 
     
     
       3. The nozzle structure of a burner of  claim 1 , wherein a handle is downward extending from a lower surface of the shielding member with a predetermined length, so as to protrude toward outside of the housing. 
     
     
       4. The nozzle structure of a burner of  claim 1 , wherein a plurality of sealing members of a ring shape are provided on an outer surface of the shielding member with a predetermined distance therebetween, in a height direction of the shielding member. 
     
     
       5. The nozzle structure of a burner of  claim 1 , wherein a stopper which protrudes with a predetermined diameter is provided at a lower circumferential surface of the shielding member, and
 wherein a lower cap having a stepped surface is coupled to a lower surface of the housing, the stepped surface configured to restrict movement of the shielding member by contacting one end of the stopper.
